    Bought this product to help clear my allergies at night while I sleep. This product has honestly made me get a better nights rest and I wake up with a clear nose. I love the light indicator that changes color based off the air's quality.

    I already have two other blue air purifiers that are larger ones for larger rooms in my home and I love how clean and fresh the air is from those so I bought this little one for my office and it does a great job in my little office it really helps during allergy season to help control the pollen

    Nice little unit. The only negative about it is that the second from the highest fan speed, is about one fourth the speed of the highest speed, but other than that, it's a good little purifier for the price!

    This product worked fantastically for almost 2 weeks, then suddenly got extremely loud and developed a rattling sound and an odd smell. None of the parts inside were individually packaged,and there was no tape over the folds. I suspect this may have been a returned item pukked accidentally and sold as new. Will be exchanging for a different model.
